BDP-S780/BDP-S790

[David_S]

I now have one of each models.  They are one year apart, the S780 is last year's model & the S790 is this year's model.  They are at the same position in the model line but have a number of differences.

Front view.  BDP-S790 on top.

Both players have front & rear USB connectors.

Top view.  BDP-S790 on top.

The BDP-S780 has 4 switches near the bottom of the front panel.  The BDP-S790 has 4 sensing spots near the front of the top cover (I/O label at left end & 3 lighted patterns near the right end).

BDP-S790 on top.  The finish of both models easily show dust specks.

Only the BDP-S780 has component video out & a Control S jack.  The S790 has 2 HDMI out vs 1 for the S780.  Remaining rear connections are identical for both players.

I purchased the BDP-S780 locally at a Sony store.  The BDP-S790 was purchased online from the US.

I have had no problems with the BDP-S780 but reported in the Sony STR-DA5700ES A/V Receiver Review thread that I had problems getting the BDP-S790.

The S790 player was returned to the sender because of an address error.  The seller quickly sent a replacement.  The replacement was a new player in the original factory sealed box.  The disc drawer would not open when I powered the BDP-S790 player & pressed the "Open" sensor.  I already had enough delays do to the postal error & decided to open the player and see if I could fix the problem, despite risking voiding the warranty.

This picture shows the piece that magnetically clamps the disc to the motor.  The magnetic clamp is dislodged from it's holder & permantly attached to the motor.  This prevents the drawer from opening.

The BDP-S790 player is back together & working properly.

Have you had a chance yet to run PCM, DTS or Dolby Digital Audio through the USB inputs of your Sony BD Players?

Hello David_S,

Could you please kindly detail for me as to how you opened the case of your BDPS790?

I tried to open mine to change out the fuse; however I couldn't figure out how to remove the plastic top and sides?

Thank you in advance,

HTinP

Are you sure it is the fuse & is your BDP-S790 out of warranty?

The S790 was a challenge to open up.  It was not straight forward to open & I will have to re-open mine to be able to describe how to take the case off.  Photos would also help.  That is a task best suited for the weekend when I have more time.

Hello again David_S,

The player was purchased in the USA and has no warrany here, so, it is just far easier to open and check the fuse than the alternative.  

Either way, I could not figure out how to open the unit without seemingly doing damage, I would really appreciate it if you could post the pictures and procedure!

Regards,

HTinP

HTinParadise-I hope this helps you.  Please let us know if you are able to solve the problem with your BDP-S790.

I thought that I should have taken an overall gut shot of the BDP-S790 when I previously had it open for repairs.  This gave me an excuse to open it up for photos.
